Abstract

Influence of temperature on corrosion inhibition for carbon steel by rice straw extract in HCl solution: Synergistic effect of cationic surfactant AIP Conf. Proc. 1571, 48 (2013); 10.1063/1.4858628The study of palm oil methyl ester and its corrosiveness AIP Conf.Abstract. The behavior of carbon steel SAE 1045 in 1 M NaOH solution containing different concentrations of palm kernel oil (PKO) has been studied by weight loss and polarization measurement. Results showed that the corrosion of carbon steel in NaOH solution was considerably reduced in presence of such inhibitors. The inhibition efficiency increases when concentration of inhibitor increase. Maximum inhibition efficiency (≈ 96.67%) is obtained at PKO concentration 8 v/v %. This result revealed that palm kernel oil can act as a corrosion inhibitor in an alkaline medium. Corrosion rates of carbon steel decrease as the concentration of inhibitor is increased.

Surface Plasmon Resonance Sensor to Detect n‐Hexane in Palm Kernel Oil Using Polypyrrole Nanoparticles Reduced Graphene Oxide Layer

“…PPy-NPs/RGO. So, the SPR signals were separately registered for each n-hexane solution, and the SPR signals were analyzed using Fresnel's equations (1), (3), and (5)- (7). The experiment was repeated 10 times to obtain the variation of resonance angle shift with time.…”

“…Palm kernel oil is rich in saturated fatty acids and a small amount of unsaturated fatty acids. Palm kernel oil is a white to yellowish oil which is solid at normal temperature and is considered a secondary product of palm fruit [1]. Palm kernel oil contains approximately 80% saturated fatty acid comprised of C12 or lauric acid (48.7%), C14 or myristic acid (15.6%), and C16 or palmitic acid (7.5%).…”
